## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 0.1.21
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

This is a real automatic agent-extension lifecycle risk, but the write scope is namespaced and the remote path is authenticated and configuration-gated. Static inspection found no secret harvesting, arbitrary shell execution during postinstall, or self-dependency chain.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Npm installation changes the consumer project's agent skill directories. With configured MCP credentials, it also obtains remote skill text and installs it for compatible agents.

- **Trigger:** Installing the package runs postinstall; remote synchronization additionally requires MCP URL and access-token environment variables.

- **Impact:** Agent instructions in the consumer project can be added or replaced without an explicit skill-install command.

- **Evidence paths:** package.json, cli/postinstall.mjs, cli/install-agent-skills.mjs, cli/install-mcp-skills.mjs, cli/mcp-platform-skills.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-11T17:47:00.930Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Automatic local and authenticated remote agent-skill installation.

- **Rationale:** This is a real automatic agent-extension lifecycle risk, but the write scope is namespaced and the remote path is authenticated and configuration-gated. Static inspection found no secret harvesting, arbitrary shell execution during postinstall, or self-dependency chain.

- **Files touched:** cli/postinstall.mjs, agent\_scaffold/skills, \<consumer project\>/.agents/skills/command-center, \<consumer project\>/.agents/skills/mainsequence

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 89.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The package runs a postinstall hook that automatically installs agent skills into the consumer project., The installer writes packaged content under the consumer project's .agents skills control surface., When configured with an MCP URL and access token, postinstall fetches remote skill content and writes it under a second agent-skill namespace.

- **Evidence against:** The remote synchronization requires both a configured URL and access token, and failures do not block installation., The installers restrict paths, reject symlinks, and use package-specific namespaces.

## Affected versions and remediation

This report applies to @dev-mainsequence/command-center-sdk@0.1.21.

- Review the evidence and your use of @dev-mainsequence/command-center-sdk@0.1.21 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
